T [Ll] whom it may concern:

Be it knownthat l; HARRY. M. Aennnnrnr, a citizen of the United States, residing at 'Cleveland, in the 'county of Guyaho a and State of Ohio, have invented new an useful Improvements in Electrical Relays, of which the following isa specification.

This invention relates to reversible-contact electrical relays; and one of the principal objects of the same is to provide an apparatus of this character in which the contact may be reversed in any of the lines from front to back without interfering with the other lines or circuits passing through the relay.

Another object is to provide a silver-plated reversible carben contactpoint and a splitspring platinum contact which will be reliside view of the platinum contactholder.'

able and efiicient inuse and which will always insure a proper operation under varying ccnditions.

Another object is to provide a multiple relay with means whereby any desirable number of lines may be provided with front orback contacts and which may either be supported upon a horizontal base or be suspended from a vertical wallor support without derangement of the working parts.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1. is a side elevation of a multiple relay made in accordance with this invention and showing one of the contacts adjusted for completing a front circuit. Fig. 2 is a detail side view showing the contact-points adjusted for making a back contact. Fig. 3 is a vertical sectional view on the line 1 1, Fig. 1.

Fig. 4 is a plan view of the relay as a whole. Fi 5 is a plan view of the adjustable carbonho der. Fig. 6 is an end view of the'same. Fig. 7 is a perspectiveview of the doublepointed contact-carbon. Fig. 8 is a detail Fig. 9 is a detail plan view of the armaturebar. Fig. 10 is a similar view of the armature-shaft.

- Referring to the accompanying drawings for a more particulardescription of my invention, the numeral 1 designates the base or support for the working parts of the apparatus/said base being made of porcelain or other non-conducting or insulating material. This base consists of a horizontal tablet 2,

" tpre therein, by means of vided with a vertical bracket back, said bracket-portion having an aperwhich the appa ra'tus may be supported from a vertical wall without derangement of the parts. Rising from the horizontal tablet 2 is an,,.integral block or support 6 for the electromagnets 7 's'aid block being provided with parallel longitudinal bores or apertures within which the magnets are supported. Depending from the rear upper endof theblock 5 is a bracket 8, and the electromagnets are supported at their rear ends upon screws 9, passing through the bracket 8 and through an insulating block 19. At the sides and at the rear of the base 1 are the curved braces 11, which connect' the horizontal tablet 2 with the bracket portion 4-. Secured on top of the block 6 is aninsulating plate or block 12, made to conform in size and shape to the top of the 'suppert 5 and to which it is secured by a series of conductor-bolts 13. The carbon-holder lei consists of a metal bar provided with a slot 15, through which the holder is secured in placeon top of the block 12. At its lront end the carboneholder has a bearing-sleeve t6, in which the silver-plated carbon point 17 is secured by a set-screw 18. It will be understcod that any desired number of the carin the present instance six beingshown, and since they-are identicalin. construction a description of one will serve as a description for all. The carbon point consists of a round piece of carbon having its opposite ends beveled, as at 19, and the entire carbon is plated with silver to increase the durability of the carborfpoints and at the same time insure smooth wearing-surfaces. The platinum contact-points each consist of a split spring 20, having an inclined portion to which the platinum plate 21 is secured. The opposite curved end of the spring is connected by a set-screw 22 to a reversible contact-hold er 23. This contact-holder is split at 24, and the spring 20 is held in theslit by the set-screw 22. A fiat shank 25 on the lower end of the holder 23 is fitted in' a slot at the upper end of the armature-bar 26 and held in place by two screws 27. At its lower end the armature supported upon feet 3 at the corners and pro-' portion 4 at the.

hon-holders may be used on the apparatus,.

bar 29 is connected by screws 28 to an insulated sh aft 29, and the ends of the shaft 29 are pivoted to rock on pointed set-screws 30, mounted in a support 31, having end bearing-lugs 82. The set-screws are provided With lock-nuts 33, by means of which the 5 screws are held against rotation When adjusted. The armature-lair 26 is enlarged near its ion tudinal center and provided with two a; "-hcies for the screws-34, the latter hrough the armature-bar, through an block. 35, and through the armaarinature is adj ustcd and ne of a spring 37, connected uch are short silk threads 38, aid t being attached to a bar secured to the armature, and the other Tread connected to an adjusting-pin "l, mounted to turn in a post 41, rising from see of" e appar. tus. An adjusting ovided with a lock-nut L3, is the post ii, and the screw 42 is it the outward throw of the e the tension of the spring 37 ed by the pin to hold the ar net and in contact a screw 42. Binding-posts he 2, and corners to inclose the apparatus. To e from front to b ack contactd'iolder 23 is ,ur bar 26 and re- .i l ig. 2, and the hltlUOLi outward, so 1 on point Will be e obvious that utilized and ad ust- 5 he carbon point .i to the required disnoni contact by means of cation, What Patent and.

versing and inverting said carbon point, a reversible platinum point, and means for adjusting the platinum point with respect to the carbon point.

3. In a relay, a carbon point reversely beveled at each end, a platinum contact mounted on a spring, means for reversing the position of the platinum contact and means for adjusting the carbon point to either position of the platinum contact.

4. In a relay, 0. double-ended carbon point mounted in an adjustable holder, a platinum contact mounted on a split spring, a reversible holder for said spring, an armature-bar carrying an armature and connected to a pivoted shaft, and means for limiting the throw of the armature.

5. In a relay, a reversible carbon point, a

reversible platinum contact, an armature,

electromagnets, a spring connected by a filament to the armature, afilament at the opposite end of the spring, and an adjusting-pin for adjusting the tension of the spring, substantially as described.

6. A multiple relay comprising an insulated base or bracket, an integral block rising from the base, electromagnets extending through. openings in said block, an integral arm depending from the rear end of said blockfor the screws to sup iort the magnets, and an integral bracket at t c rear end of said base provided with an aperture for suspending the base from a vertical support, substantially as described.

7. In a multiple relay, a base or support, a series of carbon-holders each provided with a sleeve or bearing, a double ended carbon point mounted in each of the sleeves, a series of reversible platinum contacts, each mounted on a split spring, and means for adjusting the carbon-holders independently to a position to make a front or back contact, sul

stantially as described.

8. In a multiple relay, a base or support, a series of adjustable double-ended contactpoints, a series of reversible platinum points, and means for independently adjusting the carbon points and platinum contacts to front and b acl; contacts, substantially as described.

9. In a multiple relay, a base or support, series of double-ended carbon points, a series of adjustable holders therefor, a series of platinum contacts each mounted upon a split spring, electromagnets, an armature, and an insulated spring for adjusting the throw of the armature.
